Abstract


With the rapid development of electronic technology , the types of electronic equipment more and more , they are increasingly high requirements of power , based on the power and lighter , thinner, smaller and more efficient for the development direction . Traditional linear regulated power supply can no longer meet the requirements of the switching power supply in use than linear power supply with higher efficiency and flexibility . In this paper, the design of a resonant PWM power control chip . The paper first describes the basic theory of the switching power supply , designed on the basis of the control system structure of each module circuit chip . The chip includes a precision reference voltage source , wide bandwidth error amplifier , a frequency of up to 3MHz variable frequency oscillator , dual high current totem pole output drivers and a single -shot timer . The chip output mode can be programmed to set , for example, shut down A , B Close ; A and B are closed , or A and B were closed . The chip also contains a general comparison , a fast fault detection comparator delay circuit , soft-start circuit and a reset start . In addition , the chip also includes undervoltage lockout circuit to make the output level is low and input supply current at a minimum security saving state during startup . In this paper, the system structure and function of the chip , the circuit structure and function of each module analysis and simulation results show that the indicators to achieve the design requirements to achieve the desired design goals .
